[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a diffusing device for an air freshener or the like that can forcibly diffuse air (hereinafter referred to as scent) vaporized from an air freshener or deodorant into a room by a blower.

[0002]

[Prior art]

 Conventionally, an air blower that rotates a fan with a motor is installed inside, and an air freshener or deodorant molded into a solid, liquid, or fluid is installed in the air flow path by this air blower. There were aroma devices and deodorizers that diffuse the scent of agents and the like outside the device. In these devices, a fragrance such as a fragrance was simply diffused outside the device by a fan. By the way, when these devices are used indoors, there is a regulation that the rotation noise generated by a motor or fan cannot be increased, and when air is blown to a fragrance, it is exposed to wind. It is known that the fragrance and the like gradually decrease from the side.

[0003]

[Problems to be solved by the device]

 When the amount of the fragrance or the like decreases in this way, the distance between the fan and the surface of the fragrance or the like on which the wind hits gradually increases. Therefore, if the wind force is constant, the wind force that hits the upper surface of this fragrance or the like will gradually weaken, and the amount of scent diffusion will gradually decrease.

On the other hand, although it has been considered that the wind force is gradually increased with the changing distance, in order to increase the wind force, it is necessary to increase the rotational force of the fan or the motor, which causes an adverse effect that the rotational sound becomes loud. Occurs. Furthermore, although it was considered to displace either the fan or the fragrance with the changing distance, the means for recognizing the changing distance between the fragrance and the fan and either the fragrance or the fan are displaced. The means could not be easily found.

The object of the present invention is to reduce the amount of fragrance diffused even when the amount of fragrance, etc., decreases, does not emit more than conventional rotation noise, and has a structure that is easy to produce. It is to provide a spreading device.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides an exterior housing having only an open top surface, an elastic body provided on a bottom wall in the exterior housing and elastically urging in an upper surface direction, A slidable housing that can be internally mounted and slidable, and has a ventilation opening formed on at least the upper surface, and is placed above the sliding housing and blows air toward the ventilation opening. A diffuser for fragrance or the like is provided, which is characterized in that a vertical diffusion hole is provided in a side wall of the sliding housing.

[0007]

[Action]

 In the fragrance diffuser of the present invention, a well-known fragrance or the like is installed in the sliding housing, and the ventilation opening of the sliding housing is positioned above the opening of the upper surface of the exterior housing. Interpolate from. Eventually, this sliding housing is placed in contact with the upper end of the elastic body provided on the bottom wall inside the exterior housing. On the other hand, the elastic body is elastically urged against the sliding casing due to the total weight of the aromatic casing and the sliding casing. After the sliding housing is installed in this way, if air is blown from the upper side with a blower, the fragrance diffuses and the fragrance gradually decreases from the upper surface. If there is a gap between the inner surface of the side wall of the sliding housing and the side wall of the fragrance or the like, air will blow into this gap and the side wall of the fragrance or the like will gradually decrease. It is preferable to use a fragrance or the like having a size such that the fragrance is tightly fitted to the sliding case.

[0008] The weight of the fragrance and the like gradually decreases as the amount thereof decreases. For this reason, the sliding casing is displaced upward by the elastic force of the elastic body while sliding along the side wall of the exterior casing by the amount of the lighter fragrance or the like. In this way, the distance between the upper surface of the fragrance or the like and the blower is kept constant.

Further, in the apparatus according to the second aspect, since the vertical diffusion hole is formed in the side wall of the sliding housing, the sliding housing can be displaced upward. Along with this, the diffusion hole is also covered.

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing an embodiment of a diffusing device according to the present invention, and FIG. 2 is an operation diagram thereof. First, in the figure, reference numeral 1 is an exterior housing whose top surface is only open, and 2 is an elastic body provided on a bottom wall 3 in the exterior housing 1. The outer casing 1 is formed of aluminum, synthetic resin, or the like into a quadrangular shape in plan view, a polygonal shape in plan view, or a circular shape in which only the upper surface is opened as shown in the drawing. Further, the outer casing 1 may be one in which a plate member is erected on a flat plate (not shown) and formed in a quadrangular shape in a plan view.

On the bottom wall 3 of the exterior housing 1 formed in this way, the elastic body 2 that is elastically urged toward the upper surface of the exterior housing 1 is provided. The elastic body 2 is preferably a coil spring, and the coil spring may be a cylindrical coil spring, a conical coil spring, a bamboo coil spring, a drum-shaped coil spring, or a drum-shaped coil spring.

Next, reference numeral 4 in the drawing denotes a casing body that can be installed in a state in which it is close to the exterior casing 1 and that is slidable, and has a ventilation opening 5 formed on at least the upper surface thereof. It is a case. The sliding housing 4 is formed into a housing by a well-known method using a material such as paper or synthetic resin. The shape and height of the sliding housing 4 in plan view are the same as those of the outer housing 1 in plan view and height. Depends on the size. However, conversely, it can be said that the exterior housing 1 is determined by the height of the sliding housing 4 and the shape in plan view. In any case, there is no difference in forming a casing body that can be placed in the proximity of the exterior casing 1 and can slide. Here, the close state means a state in which the sliding housing 4 and the exterior housing 1 are joined to each other such that they can slide, or a state in which they are not joined with a slight gap therebetween. In the manufacturing process, if the fragrance 6 or the like is commercialized in advance in the sliding casing 4, the sliding casing 4 itself can be used as the replaceable fragrance 6 or the like. Of course, the sliding housing 4 may be provided with an opening / closing lid or the like and the aromatic substance 6 or the like may be refilled.

A ventilation opening 5 is formed on the upper surface of the sliding housing 4. The ventilation opening 5 has a plurality of small holes as shown in the drawing, the upper surface (not shown) has a mesh shape to form the ventilation opening 5, and the upper surface is substantially completely opened to provide the ventilation opening 5. And the like are possible.

Further, a vertical diffusion hole 8 is formed in the side wall 7 of the sliding housing 4. The diffusion hole 8 is formed by forming a plurality of vertically elongated holes 8 in the upper and lower sides of the side wall 7 as shown in the figure, or one upper and lower side of the side wall 7 not shown. It is also possible to form a long hole portion 8 at the bottom, or to form one long hole portion 8 at the left and right formed on the left and right sides of the side wall 7 in series in the vertical direction.

Finally, reference numeral 9 in the figure denotes a blower that is placed above the sliding housing 4 and blows air toward the ventilation opening 5. This blower 9 uses a well-known one composed of a motor and a fan used in this type of product, and an exterior body (not shown) covering the entire device above the upper limit of sliding of the sliding housing 4. It adheres to the upper wall of the inner surface of.

The diffusion device of the present invention constructed as described above operates as shown in FIG. That is, the sliding housing 4 in which the fragrance 6 or the like is installed is inserted from the open upper surface of the outer housing 1 with the ventilation opening 5 as the upper layer. The sliding housing 4 is placed in contact with the upper end of the elastic body 2 provided on the bottom wall 3 in the exterior housing 1. On the other hand, the elastic body 2 is elastically urged against the sliding housing 4 by the total weight of the aromatic substance 6 and the sliding housing 4. The distance between the blower 9 and the upper surface of the fragrance 6 etc. in this state is defined as t. After the sliding housing 4 is installed with the elastic body 2 elastically biased in this manner, when air is blown from the upper side by the blower 9, the air blows through the ventilation opening 5 and the upper surface of the fragrance 6 or the like. Spreads the scent. This scent is diffused to the outside of the device through the diffusion hole portion 8 that is covered from the outer casing 1, or both the diffusion hole portion 8 and the ventilation opening 5.

Eventually, the fragrance 6 and the like gradually decrease, but the weight also gradually decreases with the decrease. Therefore, the sliding housing 4 is displaced upward by the elastic force of the elastic body 3 while sliding along the side wall of the exterior housing 1 by the amount that the aromatic substance 6 is lightened. However, while the sliding housing 4 is displaced upward, the upper surface of the fragrance 6 or the like is decreasing downward, so that the distance t between the upper surface of the fragrance 6 and the blower 9 is constant. The distance t will be maintained.

Further, by covering the diffusion hole portion 8 with the decrease of the aromatic substance 6 or the like, the hole 8 can be used as a scale for reducing the amount of the aromatic substance 6 or the remaining amount. it can.

[Effect of device]

 According to the diffuser of the fragrance or the like according to claim 1, when the fragrance or the like is installed in the sliding housing, the fragrance or the like can be used as long as the sliding housing is installed in the exterior housing. It is possible to block the air blow to the area other than the upper surface and reduce the fragrance and the like only from the upper surface direction to the lower surface. Further, since the outer casing also has a guide function for the sliding casing and regulates left and right swaying due to displacement of the sliding casing, the upper surface of the fragrance or the like receives air blown from the blower at the same angle, The way it decreases does not decrease at all.

Furthermore, since the total weight of the sliding housing including the fragrance and the like is reduced with the decrease of the fragrance and the like, the sliding housing is made of an elastic body to blow the blower by the reduced amount. Is displaced in the direction of. Therefore, keep the distance t from the upper surface of the fragrance etc. to the blower at the time of installation and the distance t from the upper surface of the fragrance etc. to the blower after the reduction to a constant distance until the fragrance disappears. The amount of diffusion can be constant. For this reason, the amount of scent diffused can be made constant regardless of the reduction of the fragrance and the like, and it is not necessary to increase the rotating noise of the blower even when used indoors.

Further, according to the diffusing device for the fragrance or the like according to claim 2, since the fragrance is discharged from the diffusion hole while receiving the wind from the ventilation opening for the fragrance or the like. It is possible to enhance the output effect. Further, as the fragrance and the like are reduced, the diffusion holes are gradually covered. The extent to which the diffusion holes are coated serves as a scale for recognizing the reduction amount or the remaining amount of the fragrance or the like.

It should be added that sliding the sliding housing in the horizontal direction is the same technical idea as the present invention.
